To better understand the genetic basis of human diseases, would it be better to sequence 1000 human genomes or 1000

genomes of closely related species?



a. 1000 genomes of closely related species, because animals exhibit disease symptoms more clearly than humans
do
b. 1000 genomes of closely related species, because it is easier to sequence animal genomes than human
genomes
c. 1000 human genomes, because this would give a better indication of the evolutionary history of diseasecausing
genes
d. 1000 human genomes, because this would give a better indication of the link between specific human genes
and genetic disorders
e. neither would be beneficial because human disease is almost entirely caused by environmental factors


ANSWER: d

In an experiment on the effects of deforestation of a portion of a northern temperate deciduous forest, all the trees were removed from a small mountainside watershed area and herbicides were applied for three years to prevent regrowth. Measurements of the concentration of calcium (an important nutrient) in runoff water were taken both before and after the deforestation. Monthly measurements also were made in a similar watershed in another part of the same forest that had been left undisturbed. The findings are displayed in the graph below. (There is an image in your packet #101-105) 2002 test Which of the following factors affecting the hydrologic cycle would have the LEAST impact on calcium loss from the disturbed watershed?

(A) Total precipitation (B) Surface runoff (C) Evaporation (D) Transpiration (E) Porosity of soil
